Centering a “position: absolute” element

Sometimes we have a one-line div, having 3 elements. One floats to the left, one floats to the right, and one in the middle. The one in the middle often gets pushed around by the left/right element, resulting off-centered. related question.

  

The fix is to give the following css to the center div.

position: absolute;
margin-left: auto;
margin-right: auto;
left: 0;
right: 0;

Text wrapping inside a table

Sometimes I have a long continuing string inside a table that messes up my table width. For example,

SDFSDFDGFHDGREFGFGSDFGFGHGDSFGHJTYRGHTYYEGHJTRTWEGRTYEGFHERGHRETERHRTTWERHGEWGERGW

That will give you a very wide column… Just how to squeeze the column to the width we specify?

“Easy,” you might say, “just set the td width!”

SDFSDFDGFHDGREFGFGSDFGFGHGDSFGHJTYRGHTYYEGHJTRTWEGRTYEGFHERGHRETERHRTTWERHGEWGERGW

Nope. It turns out the same, one long continuous string.

The root problem here is that, the table width is determined by the content, but not the width we specify!

There is this css attribute for the table called table-layout, it disables the usual auto-layout and follows the widths specified. Thus our table will not be shaped by the table content.

SDFSDFDGFHDGREFGFGSDFGFGHGDSFGHJTYRGHTYYEGHJTRTWEGRTYEGFHERGHRETERHRTTWERHGEWGERGW

OK… So our column now has the specified width, but now the long string goes out of the table column. The content spills over. Even though this is the default behavior in html, it doesn’t look right.

Luckily there is this css attribute called word-wrap. Its function is to break up long continuous words.

So there you have it, table-layout: fixed and word-wrap: break-word will fix the issue.

Adding shadow to wp-codebox

Too bad wp-codebox contains two divs namely wp_codebox_msgheader and wp_codebox, we cannot simply give the box-shadow to one single div. After playing with this a bit, here is my parameters. The css file is located at /your-wp-root/wp-content/plugins/wp-codebox/css/codebox.css.

.wp_codebox_msgheader {
        box-shadow: 6px 14px 11px #808083;
}
.wp_codebox {
        box-shadow: 7px 10px 10px #888;
}

The overlapped area seems smooth with this setting.

I also added bottom margin to the codebox, see if you like it.

.wp_codebox {
        margin-bottom: 20px;
}

PSD to CSS

I found this nice video tutorial recently. Say you hire someone or somehow you have a website design on a psd file, now you need to convert that to actual webpages. You can actually do that yourself without getting other people to do it. It might be much easier than you think!

I am assuming you already have some knowledge in HTML and CSS… if not… it’s a good idea to learn them! 😉

Step 1: Writing the Markup

Step 2: Coding the CSS
